August Lock: Motor Losing Power Diagnostic

Diagnosing August Lock motor power issues in Canadian homes. Troubleshooting steps, safety warnings, and expert tips for optimal performance.

Frequently Asked Questions

•How do I check for door frame warping?

Visually inspect the alignment between the door and the frame. Use a level to check for vertical or horizontal deviations. Look for gaps or areas where the door rubs against the frame.

•What type of lubricant is best for the deadbolt?

Use a silicone-based lubricant, as it won't attract dust or debris. Avoid using petroleum-based lubricants, as they can damage the lock mechanism over time. Apply the lubricant sparingly to the moving parts of the deadbolt.

•How do I reset my August Connect bridge?

Locate the reset button on the August Connect bridge (usually on the back or bottom). Press and hold the reset button for 5-10 seconds until the LED indicator starts flashing. Refer to the August support website for detailed instructions.

Why This Happens:

Low battery voltage, especially during cold Canadian winters where battery impedance increases.
Mechanical binding in the deadbolt mechanism or door frame due to warping from seasonal temperature changes.
Wireless interference (2.4GHz) from nearby devices affecting communication between the lock and the bridge.
Worn or damaged motor components requiring excessive current to operate.
Insufficient power from the C-wire if installed (check voltage and wiring).
Firmware bugs causing incorrect motor control parameters.

Important Warnings:

Do not attempt to disassemble the August lock motor. This can result in damage or injury. Secure data privacy by enabling two-factor authentication. Protect the August lock from physical tampering. Dispose of used batteries according to local Canadian regulations.

Recommended Action:

1

Replace batteries with new, high-quality alkaline or lithium batteries, noting the polarity. Check the battery voltage with a multimeter (should be above 1.5V per cell under load).
2

Inspect the deadbolt and strike plate for obstructions or misalignment. Lubricate the deadbolt mechanism with silicone-based lubricant. Ensure smooth operation.
3

Use a Wi-Fi analyzer app to check for 2.4 GHz interference. Move the August Connect bridge closer to the lock and away from other wireless devices. Change Wi-Fi channel on your Bell Giga Hub/Rogers Ignite router.
4

Check C-wire voltage with a multimeter (should be 24VAC). Inspect C-wire connections for corrosion or loose wiring.
5

Perform a factory reset of the August lock (refer to the August support website for the correct procedure).
6

Update the August lock firmware to the latest version using the August app.
7

If the problem persists, contact August support or a qualified locksmith for motor replacement.

What to Look For:

Motor operation sounds weak or intermittent. Lock fails to fully extend or retract the bolt. LED indicator flashes red or displays a low-battery warning, even after battery replacement. App reports motor error or calibration failure. Door may not lock or unlock remotely.

Technical Recommendation:

Try temporarily disabling Bluetooth on your phone during lock/unlock operations to force the lock to use Wi-Fi. This can help isolate RF interference issues, especially if the Bluetooth radio is malfunctioning. Use a non-contact voltage tester near the C-wire connection to confirm it is properly connected.

Technical Background:

The August lock relies on a DC motor to actuate the deadbolt. This motor is powered by batteries (typically AA or CR123A) and controlled by a microcontroller. Motor current draw increases significantly during lock/unlock cycles. The system communicates wirelessly (Wi-Fi, Z-Wave, or Bluetooth) with the August Connect bridge and the user's smartphone app. Weak batteries or mechanical resistance will increase motor current and decrease available torque.

Preventative Care:

Replace batteries every 6-12 months, especially before the onset of winter.
Regularly lubricate the deadbolt mechanism.
Monitor battery levels through the August app.
Keep the August Connect bridge firmware updated.
Check door alignment twice a year (spring and fall) to prevent mechanical binding.
